The co-founders of No Excuses PAC — Saikat Chakrabarti, Corbin Trent and Zack Exley — are starting a search for candidates to challenge incumbent Democrats they say are standing in the way of ambitious action to end the coronavirus pandemic and revive the economy…

Manchin and Sinema’s opposition to eliminating the legislative filibuster — which requires a 60-vote threshold for most legislation — is the main reason No Excuses is putting a call out for possible challengers. Progressives have increasingly pressed Senate Democrats and President Joe Biden to end the filibuster, arguing that in an evenly divided Senate it will be nearly impossible to find enough Republicans to pass major pieces of Biden’s agenda.

“The only real way to pressure any of these folks and hold them accountable to their promises is to threaten their power, and threaten the seat that they hold and threaten their reelection,” said Chakrabarti, who is also a former chief-of-staff to Ocasio-Cortez. “We sort of have this theory that the voters in Arizona and the voters in West Virginia would care more about action, they care more about jobs and their community and money in their pockets than they do about an arcane Senate rule called the filibuster.”
